Can I use a Revolut account to prove funds for my visa application in Thailand?

Yes. Easy

Yes I had the money in my Thai account wouldn't accept that so I transfers to my revolute and was no issue

Yes, I used it twice for a METV, no problem at all

I would move the money from revolut to a normal account and wait for it to be seasoned 3-6 months depending where you apply. STAY SIMPLE THE MOMENT YOUS STORY BECOMES COMPLICATED SO WILL THE APPROVAL FOR THIS VISA. They will require you to send extra documents etc. I get that revolut gives you a better interest and flexibility but for the visa purposes they are more interest in how finantially stable you are. Someone that gets paid on a montly basis will use revolut as a tool for not having a bank account. But having this as a FULL TIME bank account could raise doubts about your financial stability. If the financials are not in line with the requirements get a sponsor with a season account outside of thailand that can help you satisfy the financial requirement . All the best 🙏

It depends, revolut is a bank in some countries but not in others

Yes, it works every time. Most of my clients use Revolut for proof of funds.

Yes, Revolters have got approved for a DTV.
